PAPER-FOLDING MACHINE.

SPECIFICATION ozmng part of Letters Patent No. 377.354, dated January31, 1888.

Application filed June 2,188?.

TO all whom it may concer:

Be it known that I, XVE'LLINGTON DOWN- ING, a citizen of the UnitedStates, residing at Erie, in the County of Erie and State ofPennsylvania,have invented certain new and useful Improvements inPaper-Folding Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention,such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to paper-folding machines; and it consists incertain improvenents in the Construction of the feeding-table, as willbe hereinafter fully described, and pointed out in the claims.

My invention is illustrated iu the accompa nying drawings, as follows:

Figurelisaperspective Viewshowingthetop and afragment of the frameworkofa foldingmachine with my invention embodied therein.

Fig. 2 is a plan view of the under side of the *feeding-table and itssupports. Fig. 3 is a transverse section of the parts shown in Fig. 2 ontheline y y in said figure. Fig.tisa1ongitudinal section of the sameparts on the line x a; in said figure.

A marks the framework of the machine; A', the bracket or support of thefeeding-table; B, the starter or foldingblade; C G, the top of thefoldingmachine; c c, the points to which the paper is adjusted before itis folded; D, the first pair of folding-rollers; E, the feeding-table; GG, i'acks on the under side of the feeding-table; F pinions which gearwith the said racks; F, a shaft carrying said pinions, and F' ahand-wheel for operating said shaft.

The feedngtable E is supported on the brackets A' A' a little above thetop C of the folder, and it is adjusted on said brackets so as toslidelongitudinally thereon, and thereby be approached more or lesstoward the folding-roller D. In Fig. l dotted lines show thefeeding-table approached closely to the said rolls, and in full lines itis shown removed at a considerable distance fron said rolls. Thefeeding-table can be made so as to be moved longitudinally by hand or bymechanism. I illustrate one plan for Operating it by nech- Serial No.240046. (No model.)

anisn. This consists in providing racks G G on the under side of thetable and journaling in the brackets A' a shaft, F, with pinions Fthereon, which gear with the said racks, and providing said shaft with ahand-wheel by which it can be revolved. NVhen the feedingtable is thusprovided with mechanisn for moving it longitudinally, very littletrouble will be experienced in adjusting the table to any point desired.

The object in constructng the feeding-table so it can be adjusted moreor less near the feeding-rollers D is to enable the operator to bringthe pile of unfolded sheets on the table into the most convenientposition for feeding them to the machine. The operator sits or stands atone side of the machine, about op posite the ends of thefolding-rollers, and the nearer the papers on the feeding-table are tothe operator the better. The table must of necessity be removed a littlemore than onehalf the length of the sheets from the feeding-rollers, andit has been the practice to fix a table far enough away from theserollers to accommodate large sheets; but when the operator is feedingsmall sheets it is very inconvenient to be compelled to reach for thesame distance he has to when feedng large sheets. To avoid thisinconvenience I make the table adj nstable from and toward thefolding-rollers, as above explained.

What I claim as new is- 1. In a paper-folding machine, the combination,with the first set of folding-rollers, of a feeding-table that isadjustable from and toward said rollers over the top of thefoldingmachine, substantially as and for the purposes set forth.

2. In a paper-folding machine, the combination, with the first set offolding-rollers, of a feeding-table which is monnted on ways, in amanner substantially as shown, whereby it can be adjusted more or lessnear said rollers.

3. Ina paper-folding machine, the combination, with the first set offolding-rollers, of a feeding-table which is mountcd on ways and isprovided with gearing. snbstantially as set forth, whereby the saidtable can be noved on said ways and adjusted more or less near the saidfolding-rollers.
